[0023] In order to further explain the technical scheme of the present application, the present application will be described in detail below through specific embodiments.
[0024] The low-voltage drawer-type switch cabinet full-automatic unlocking execution mechanism disclosed in the embodiment is like Figure 2 and Figure 3As shown, it is installed on the end of the mechanical arm of the inspection robot during use, and performs fully automatic work, and is mainly used for performing drawer pulling operation of the drawer switch cabinet. As shown, it comprises a base 4, a knob module 5, a button module 6, a pulling module 7, a connecting action structure 8, and a supporting module 9. The base 4 is provided for mounting and connecting the module components. The knob module 5 is used for rotating the knob switch. The button module 6 is used for pressing the push switch 2. The pulling module 7 is used for pulling the drawer handle 3 of the drawer switch cabinet. The connecting action structure is used for stably connecting and smoothly moving each module on the base 4. The supporting module 9 is used for stably supporting the switch cabinet during operation. If the whole switch cabinet is stable, the supporting module 9 can not be provided. The specific structure and position connection relationship of each module structure will be described in detail below in combination with the drawings.
[0025] As shown, the base 4 is a flat panel support, and the side facing the drawer switch cabinet is the working front end during use. The pulling module 7 is fixedly connected to the working front end of the base 4 in the direction corresponding to the two handles 3 of the drawer switch cabinet (as shown in Figure 1 The structure of the pulling module 7 is configured to be embedded in the handle 3 of the drawer switch cabinet and hooked on the handle 3, which is an L-shaped structure. One end of the L-shaped arm is fixedly connected to the base 4, and the other end faces downward. During use, the arm facing downward is embedded in the handle 3 and hooked on the handle 3 to pull out the drawer.
[0026] The connecting action structure 8 comprises a first sliding guide structure 81, a first moving seat 82, a second sliding guide structure 83, a second moving seat 84, and a driving moving transmission structure 85. The first moving seat 82 is arranged on the base 4 through the first sliding guide structure 81 and is configured to slide in and out relative to the working front end. The second moving seat 84 is arranged on the first moving seat 82 through the second sliding guide structure 83 and is configured to slide in and out relative to the working front end. The knob module 5 is arranged on the second moving seat 84. The working end of the knob module for rotating the knob switch 1 faces the working front end. In this embodiment, the knob module 5 adopts a rotary electric claw (existing product, which can be directly purchased in the market) with an output end capable of clamping the knob. The rotary electric claw clamps and rotates the knob switch 1 through the electric clamping jaw, so as to realize the rotation unlocking of the knob switch. The button module 6 in this embodiment adopts an electric push rod (existing product, which can be directly purchased in the market) with a pressing end arranged on the base 4. The pressing end can be arranged corresponding to the push switch 2 of the drawer switch cabinet (as shown in Figure 1 The electric push rod has a telescopic stroke, which can facilitate the simplification of the unlocking action structure and ensure the accuracy and reliability of the action.
[0027] The driving movement transmission structure 85 is arranged on the base 4, the first movement seat 82 and the second movement seat 84 to drive the first movement seat 82 and the second movement seat 84 to slide in and out. In this embodiment, the specific structure is arranged as follows: the motor 851 is fixedly arranged on the first movement seat 82, the transmission gear 852 is fixedly arranged on the output shaft of the motor 851, the first rack 853 is fixedly arranged on the base 4 along the sliding direction of the first movement seat 82 and is engaged with the transmission gear 852, and the second rack 854 is fixedly arranged on the second movement seat 84 along the sliding direction of the second movement seat 84 and is engaged with the transmission gear 852. Through this structure, the unlocking execution mechanism can not only move under the driving of the robot arm but also drive the first movement seat 82 to slide in and out under the engagement of the transmission gear 852 and the first rack 853 and drive the second movement seat 84 to slide in and out under the engagement of the transmission gear 852 and the second rack 854 to reach the relative position between the action module and the drawer panel, so that the action module can act after reaching the working position.
[0028] In addition, the support module 9 in this embodiment is arranged on the first movement seat 82 as support legs, which are arranged towards the working front end. As shown in the figure, the support legs are arranged to correspond to the positions of the panels outside the left and right sides of the drawer panel of the drawer switch cabinet during use. The two support legs can provide a reverse supporting force for the switch cabinet during the drawer pulling to make the drawer pulling and unlocking action stable.
[0029] The above structure of the unlocking execution mechanism can realize the unlocking and pulling out of the drawer switch cabinet through the sequential action of the robot arm, the motor and the pneumatic components controlled by the system. The control of these actions can further realize accurate positioning sensing control through the movement positioning sensing structure 86 arranged between the first movement seat 82 and the base 4 and between the first movement seat 82 and the second movement seat 84. In addition, the adjustment and positioning of the relative position of the action and the switch cabinet before the action can be realized through the positioning module 10 such as a visual camera. As shown in the figure, a visual camera is arranged on the first movement seat 82.
[0030] The low-voltage drawer type switch cabinet full-automatic unlocking executing mechanism of the application can be used as follows: first, a visual camera is used to identify the features on the switch cabinet to determine the relative position of the unlocking executing mechanism and the switch cabinet; then the unlocking executing mechanism makes the rotating electric claw correspond to the front of the rotating switch; then under the driving of the motor, the support foot and the rotating electric claw are moved forward through the cooperation of the gear and the rack, so that the support foot contacts the switch cabinet, and the rotating electric claw clamps the rotating switch; the rotating electric claw is rotated by 90 degrees to drive the rotating switch to rotate by 90 degrees, so that the rotating switch is opened; then the unlocking executing mechanism is moved downward as a whole, so that the stretching module clamps the handle; then the electric push rod is moved forward to press the switch; then the unlocking executing mechanism is moved backward as a whole, so that the switch cabinet is unlocked.
[0031] The above embodiments and drawings are not limited to the product shape and style of the application, and any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the application.
